DCOM Error 10016

The description of this error in the system log is:

The application-specific permission settings do not grant Local Activation
permission for the COM Server application with CLSID
{BA126AD1-2166-11D1-B1D0-00805FC1270E}
to the user NT AUTHORITY\NETWORK SERVICE SID (S-1-5-20). This security
permission can be modified using the Component Services administrative tool.

The help reads as follows:

1. Using Regedit, navigate to the following registry value
HKCR\Clsid\clsid value\localserver32
The clsid value is the information displayed in the message.
2. In the right pane, double-click Default. The Edit String dialog box is
displayed. Leave this dialog box open.
3. Click Start, and then click Control Panel.
Double-click Administrative Tools, and then double-click Component Services.
4. In the Component Services snap-in, expand Computers, expand My Computer,
and double-click DCOM Config.
5. In the right pane, locate the program by using its friendly name.
Right-click the program name, and then select Properties.
6. On the Security tab, in the Launch and Activation Permissions group box,
select Customize, and then click Edit.
Add the user to the permissions list, and give the user the appropriate
permissions.

But here is what i find in the registry as sub-keys for this value:
(default ) Network Connection Manager Class
AppID {27AF75ED-20D9-11D1-B1CE-00805FC1270E}

there is no localserver32 key.

If I ignore that silly aspect and try and find Network Connection Manger
Class, I cannot. Even more baffleing to me is how to add NT
AUTHORITY\NETWORK SERVICE as a user if I try to customize permissions on any
DCOM class.

This is a Windows 2003 server running ISA 2004. It has two NIC cards in it,
one with a 192.168.12.1 address for the inside network and the other with a
public address in Internet space. As far as I can tell , all the ISA
functions are doing just fine. It links to another remote domain, supports
the published servers, etc.

However, the internal clients are really suffering from network pauses.
Every minute or so, clients lose connection to Exchange server, then it
recovers. Launching web browsers will sometimes take a minute or so to
initialize. Occassionaly - every so often all day long - machines will
freeze for between 5 and 30 seconds.

There are no other errors being logged on any other servers or clients, only
on the ISA machine. During these "blackout" intervals, there seems to be no
or very little network traffic. There is no conclusive proof one way or the
other that the timing of blackouts or slowdowns is the same for all clients
or is independent of one another.

Search after search using all sorts of keywords has turned up nothing of
substance. Any help would be much appreciated, including is this an ISA or a
Windows problem.

Thanks in advance.

Hi LarryH,
I have this exact event being logged every 10 mins or so but have to say we are not suffering any network issues so i think this may be a red herring to your "blackout" problem. Much more likely is the correct gateway, DNS and general network config. The server giving me this error does not have ISA or exchange, just AD with WSS installed.
Hope this helps to focus on the problem?

Thanks, Andy.

Interestingly, my network delay problems disappeared as magically as they
arose.

Still getting the DCOM message with about the same frequency as you do.

To fix this I had to do the following

Start > Administrative Tools > Component Services

In Component Services

Expand:

Component Services > Computers > My Computer > DCOM Config

Select “netman” from the list in the right window.

Right click “netman” select “properties”

In the “Netman Properties” window select the “Security” tab.

In the “Security” tab look for “Launch and Activation Permissions”. Select
Customize then click on the “Edit” Button.

In the “Launch Permissions” window click on the “Add” button.

Type in “Network Service” in the “Enter the object names to select” box.

Click on the “Ok” button.

Select the “Network Service” in the Launch Permission “Security” Tab, Group
or user names area and give it (allow rights) for “Local Launch” and “Local
Activation”

Click “Ok”
Click “Ok”

Close Component Services.

Check the event view to make sure the errors stop occurring.

Thanks for that. I was actually suspicious it was Netman but I wasn't sure.

I applied the security settings and havent seen a repeat of the error post
for the past hour or so. I will check in the morning.

Great of you to share that.

I get this same error although when it happens, my screen goes black and my computer freezes up. I then have to restart it, only to find those errors. Now my computer has been locking up on me for a month and a half. And I've been to lazy to really fix it. I've tried a bunch of things like reinstalling windows, updating drivers, and such. I tried that trouble shooting idea, and let you know if it works. What I wouldn't get is, why even after a fresh install of windows, it would be configured the same?

Hey, it's Windows! I went through all the same hoops, removing and
re-installing components. The fix described just took a minute or so and has
stuck.

It's still happening, and I'm getting the same error. I am not at home anymore, but I will post screen shots to verify my settings. I am pretty certain I am doing everything correctly. I am so frustrated. Could this be hardware? I was thinking maybe my Powersupply is on the blitz.
